` To tl/3 whom it may concern.-

tive view of the end of a spring.

Beit known that l, CnRisrorHRR C. BRAD- LEY, of the city of Syracuse, in the county of Onondaga and State of New York, have invented new and useful Improvement-s in Carriego-Springs, of which the following is a speciiication'.

This invention relates to an improvement in 'that class of carriagesprings which are provided at their ends with trunnions resting in sockets orbearings formed in couplings, Wherehy the side and end springs are connected, or by which the springs are attached to the bol- Fig. 2 is a perspective view of the joint With the end spring removed. Fig. 3 is a perspec- Fig. 4 is a sectional elevation in the line of one of the trunnions. Fig. 5 is a top plan view of the connected ends of two springs. Fig. 6 is a side elevation showinga slightly-modiiied construction of my improvements. Fig. 7 is an end elevation of the'spring in the last-named construction. l 4

Like letters of reference refer to. like parts in the several figures.

Arepresents the cross or end spring, and B the side spring, of a vehicle; and a and l represent the trunnions or journals formed, respectively, on theends oi' the springs A and B.

C represents a coupling, whereby the adj acent ends of an end and a side spring are conneeted together. with tivo sockets, d and e, arranged at right angles to each other, and one above the other,

so as to receive the trunnions u, and b. Each socket is constructed with a smooth inner bearing-surface and a closed cuter end, which latter covers the end of the trunnion and ex- 'lhe coupling Gis provided the trnnnion and socket. The inner bearingsurface of the socket "may be formed of the metal of which the coupling is constructed; but I prefer to line the socket with a cylinder,

7 Jscented in a recess, g, formed in the socket, and which nts snugly around the trunnion.

h represents a collar or shoulder formed on each spring between its blade and trunnion; and I isan ear or lug formed on such colla-r, or otherwise secured to the spring at right angles to the trunnion. r

J is aonrved lip formed on the coupling C, so as to bear against the rear side of the ear I when the trunnion is inserted in the socket and the spring and socket are in their normal position. A space or groove, z', is formed between the lip J and the body of the socket for the reception ofthe ear I. The latter and the lip J are so arranged on 'their respective supporting parts that the lip J will bear against the ear I when the spring and socket are in their normal position, thereby securing the trunnion in its socket in this position of the parts, while permitting the requisite limited turning movement of the trunnion in its socket to enable the spring to adapt itself :freelyV to the movements of the vehicle. Upon turning the spring or the socket so as to disengage the lip J and ear I from each other, the trunnion can be Withdrawn from the socket.

In the construction representedin Fi gs. 1 to 5 each spring is provided with one ear I, and each socket with one lip J. In the modication represented in Figs. 6 and 7 each spring is provided with three ears I, and each socket with three lips J.

' K represents a Washer of rubber, leather, or other yielding material arranged in the socket between the end of the trunnion and the end of the socket. This Washer is compressed in inserting the trunnion uinto the socket and takes up any longitudinal play which the ear I may have in the space i, in which it moves, thereby insuring a snug iit of the ear I in the space I have illustrated my improvements as ap plied to a coupling which connects the ends of two springs; but they are equally applicable to sockets which are secured to the ends of bolsters and other spring-supports.

My improvements furnish a socket with a cludes dust, &c., from the bearing-surfaces of of leather or other soft material, which is IOO 2 l y Y 305,888.

smooth inner bearing-surface, in which the4 trunnion of the spring turns' freely without causing anylengthwise movement of the parts, and in which the bearing-surfaces are cornpletely inclosed, and thereby protected against dust, Src., and in which the parts are held snugly, so as to be noiseless in use.

I claim as my invention-- 1. The combination, with a carriage-spring having a trunnion at its end and a socket in which said trunnion is seated, of interlocking parts formed, respectively, on the trunnion Vand socket and securing the spring and socket together when these parts are in their normal position,while permitting the parts to be separated upon placing them in an abnormal position, substantially as set forth.

2,. The combination, with a carriagespri-ng having at its end a trunnion and a projecting ear, of a socket having at its inner end a projecting lip adapted to bear against said ear,

I whereby the socket and spring are secured together in the normal position of' the parts, While permitting the trunnion to be withdrawn from the socket upon placing the parts in an abnormal position, substantially as set forth.

3. The combination, with a carriage-spring having at its end'a trunnion and a projecting ear, of a socket having a closed outer end, and provided at its inner end with a lip bearing against the ear of the spring in the normal position of the parts, substantially as set forth.

4. The combination, with a spring having a trunnion at its end, of a socket having a closed outer end, a yielding washer interposed between the ends of the trunnion and socket, andinterlocking parts formed on the socket and spring near the inner end' of the socket,
